Finally got an AR! - First Shoot went well

Anderson Arms - with a cheap CenterPoint Mini Reflex. Shot 150 rds today, was happy with my first time shooting an AR. http://imgur.com/a/PXwXf ... the zombie was at 25yds offhand, and the center mass on the silhouette was at 75.

Sighted in at 25yds on a rest, then took it offhand. Did notice some trigger creep on the pins, so going to order some anti-rotation pins. Already have some flip up BUIS on the way. The cheapo reflex was to get me out there (can't find gas block height irons locally, what a pain) - but with these results, I may keep it until I get Nikon P-223 1.5-4.5x20 I really want.
